5,5'-Carbonyldi(2-benzofuran-1,3-dione)--1-(4-aminophenyl)-1,3,3-trimethyl-2,3-dihydro-1H-inden-5-amine (1/1)

VerwendenPolyimides (PI, also known by alternative brand names: Pyralin Apical, Kapton, and Kaptrex) are polymers made of imide monomers (two carbonyl groups bonded to nitrogen). It has a density of 1430 kg/m3, Young’s modulus 3200 MPa, tensile strength (75–90) MPa, glass transition temperature > 400℃, thermal conductivity of 0.53 W/(m K), and a low relative dielectric constant of 2.9. Polyimides have applications similar to BCBs and also find applications as a low dielectric constant material in high-frequency interconnects (low-k material). The higher thermal conductivity and high glass transition temperature when compared to other types of insulating polymers also makes them a good choice where heat dissipation is important or other applications requiring good thermal management or low parasitic capacitances. Microchannels and high-frequency microdevices embedded in both photosensitive and nonphotosensitive polyimides have been fabricated and reported.
